December in the Purple Martin's year

December is the start of the true winter season. Birds are settled into winter ranges and flocking behavior peaks — mixed flocks move through woods and yards together, and feeding stations become social hubs. Short days mean birds must find most of their food in a few hours of daylight.

For the Purple Martin specifically, December is a winter month of relative routine, with the species settled into its seasonal pattern across its range. Across the 47 states and provinces where purple martins occur, what the bird is doing this month depends heavily on latitude — the details below break it down by band.

Where purple martins are in December

Southern states

Mid-latitudes

Northern states & Canada
absent

In December, purple martins are absent in the South, mostly absent (migration only) across the mid-latitudes, and absent in the northern states and Canada. That north–south split is the defining feature of this month: where you live changes which version of this bird you're looking at.

Nesting in December

Purple martins are not nesting in December. The season runs May–July at mid-latitudes.

That makes December a useful month for nest-box work: cleaning out old nesting material, checking mounts and predator guards, and making repairs while boxes are empty. A box that's ready early gets claimed early.

What to feed in December

  • Winters in South America — none in North America

Purple Martins do not use feeders. Supporting them means supplying correctly built colony housing in the open and managing House Sparrows and starlings.

Feeders are busiest at dawn and dusk as birds fuel up against long cold nights. Suet and other high-fat foods earn their keep this month.

Watching purple martins this month

Purple martins are settled and predictable in December, which makes this a good month to learn the bird's routine — same feeders, same perches, same times of day.

If you have a Purple Martin box up, this is the month to make sure it's clean, secure and ready — the box guide below has the exact hole size and mounting height this species needs.
